Abstract
A minute capacitance element has a high accuracy capacitance and is resistant to external noises. The minute capacitance element includes: first and second metal electrodes having respective opposite facets facing each other formed on an insulator layer to define a first gap therebetween; and a shield electrode being connectable to an externally applied potential and formed on the insulator layer within the first gap to define a slit confining a synthetic capacitance.
